(Optional) Installing a lightning arrester for a network port
IMPORTANT:
Read the instructions for the lightning arrester carefully before you install it.
No lightning arrester is provided with the firewall. Purchase one as needed.
If part of the network cable of an Ethernet port must be routed outdoors, connect a lightning arrester
to the cable before you plug the cable into the port. If more than one Ethernet ports on the firewall are
connected with network cables routed outdoors, connect a lightning arrester to each cable.
(Optional) Installing a lightning arrester for an AC power
module
No lightning arrester is provided with the firewall. Purchase one as needed.
If part of the AC power cord is routed outdoors, install a lightning arrester to the power input end to
protect the firewall from being damaged by lightning strikes. You can attach the lightning arrester for
AC power modules to the rack or a wall of the equipment room.
For more information about how to install and maintain a lightning arrester for AC power modules,
see the documents provided with the lightning arrester.
